Title: Method for detecting and compensating zero-point error of torque sensor
Inventor: NAKAMOTO AKIRA
IPC: G01L25/00
Filed: 1991-12-03
Abstract: PURPOSE:To enable a zero-point error to be detected and compensated easily and positively by turning on power of an electrical circuit for a torque sensor, comparing a torque signal value after a certain amount of time passes with a set value, determining it to be a zero-point abnormality if the set value is exceeded, and using the signal value as a zero-point value of detection torque signal if it is equal to or less than the set value. CONSTITUTION:A torque signal (V1-V2)t0 at a lapse of a certain amount of time t0 after power is turned on is stored in memory. When the absolute value is equal to or less than a set value alpha0. the succeeding torque value is calculated with (V1-V2)t0 as a zero point. On the other hand, when the absolute value exceeds the set value alpha0 it is judged to be the zero-point abnormality and then a zero-point abnormality signal is output. When the torque signal (V1-V2)t is not larger than a first zero-point memory (V1-V2) by a certain value or more, the torque signal (V1-V2)t does not change greatly within a certain amount of time TO. and it does not vibrate. a zero-point memory value Vzero is updated to be Vzero=(V1-V2)t0+T and the zero-point value is compensated at a lapse of a certain amount of time T at time t0.

Title: Antiskid controller
Inventor: SAKANO MASAKI
IPC: B60T8/58
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To suppress on/off drive of a solenoid switch valve for pressure reduction by changing pressure reduction of a wheel brake pressure by means of a brake pressure control means into pressure retention when a pressure reduction quantity computed by means of a pressure reduction computing means, which estimates the pressure reduction quantity of a wheel brake pressure, is the predetermined value or more. SOLUTION: When a control pattern for a wheel cylinder of a front left wheel FL shows quick pressure reduction or pulse pressure reduction, it is checked whether an output to a solenoid valve shows ON (whether an output mode shows pressure reduction) or not (step 62), and if a pressure reduction time FLT is the predetermined value Tr or more, data indicating a retention pattern is written in a control pattern register for FL (step 67) for changing a decision control pattern (quick pressure reduction or pulse pressure reduction) based on the front left wheel FL control computing into a retention pattern. When a pressure reduction time FLT is less than a set value Tr, the pressure reduction time FLT (data FLT for a pressure reduction time register FLT) is increased by one increment (counted up) (step 64).

IPC: H04J13/00
Filed: 1997-11-20
Abstract: PROBLEM TO BE SOLVED: To provide a digital modulation demodulation system for radio communication where error hardly takes place in fading while keeping a feature of the M-ary modulation demodulation system immune to interference. SOLUTION: A division section 5 divides transmission information into blocks each consisting of LN bits and further divides each block into N L-bits information series. Each M-ary coder 2 generates an M-ary orthogonal code for each L-bits information series. N-sets of orthogonal codes per block are multiplexed, each orthogonal code is spreaded into a length multiplica by N on a time base, and the carrier is digitally modulated by the multiplexed signal in order to be transmitted. A synchronization detector 3 at a receiver side detects a reception signal, a detection output is demultiplexed into N-sets of orthogonal codes, each M-ary decoder 4 determines correlation of each orthogonal code and discriminates an orthogonal code having the highest correlation, and the signal is demodulated. The L-bits information series corresponding to the orthogonal code are outputted, and the outputted N L-bits information series are restored to a signal in LN bits per reception unit.
